Application iledApril 1l, 1905. Serial No. 255,059.

This invention is a horse-rake characterized b v improvements in the means for tripping the d raft-dump.

The object of the invention is to enable the operator to work the rake successfully without removing his foot from the pedal which controls the trip. l

A further object is to provide means for holding' the teeth to the ground without effort by the operator.

A further object is to form improved means for engaging and disengaging the pawl and ratchet which operates the dump.

The invention is illustrated in the accompanying drawings, in whichA Figure 1 is a plan view of a rake provided with my improvement. Fig. 2 is a vertical sectional view showing the position of the parts before the dump is tripped. Fig. 3 is asimilar view showing theposition of the parts after the dump is tripped. Fig. 4' is a detail in plan, partly in section, showing an adjustable stop and associated parts. Fig. 5 is a section on the line 5 5 of Fig. 4. Fig. 6 is a detail. partly in section, showing the manner of attaching the rake-head to the other axles. Fig. 7 is a detail in elevation, showing the latch-link and its detent. Fig. 8 is adetail in plan of the treadle and parts carried thereby.

Referring speciiically to the drawings, 6 indicates the short wheel-axles, having thereon wheels the hubs of which carry the ratchets 7. 8 is a rake-head secured at the ends to said axles and mounted to rock thereon and having secured thereto the teeth 9. The head has a projecting arm 10, connected to a slotted link 11, having' at its lower' edge a series of forwardly-presented notches 12 and at the upper edge of the slot a series of backwardlypresented notches 13. The link works through a guide-loop 11, supported on the frame of the rake.

14 indicates a bar extending' along the upper side of the rake-head and having' at the ends7 pawls 15, arranged to engage the ratchets 16 indicates a pedal pivoted at the top of a bracket 17, supported on the frame 18 of the rake, and this pedal has extending from one side thereof a cranked rod 19, which projects into the slot in the link 11 in position to engage in the notches 13.

20 indicates a stop-pin projecting from the side of the pedal 16 in position to support the crank 19 when it swings back.

At 12L is indicated a detent secured to the frame and arranged to engag'e in one of the notches 12.

Depending from the pedal is an arm 21, connected to a rod 22, which works through a guide 23 and hole in the upturned flange of the angle-iron frame of the machine in position to strike the lower end of a metal spring'- arm 24, which is secured at its upper end to the rocking bar 14.

v25 indicates a segmental bracket corresponding in curvature to the movement of the arm 24 when the rake is dumped and carrying an adjustable stop 26 in position to strike the end of said arm 24. The rocking bar 14 has a counterweight 27, tending to disengage the pawl 15 from the ratchet-wheel.

In operation the rake is normally dropped and held down by engagement of the detent 12 in one of the notches 12. When it is desired to dump the rake, the pedal 16 is tipped downwardly and forwardly. This turns the crank 19.and lifts the link 11 out of engagement with the detent 12a. At the same time it pushes back the rod 22, which strikes the lower end of the arm 24 and rocks the bar 14 so that the pawls 15 engage in the teeth of the ratchets 7. The effect of this is to couple the ratchet and rake-head and swing the latter forwardly to dump the rake, the link 11 sliding forwardly through the guide 11. When the arm 24 strikes the stop, the movement of the pawl with the ratchet is arrested and the pawl is turned out or back and disengaged from the ratchet, which allows the rake to drop to the ground. As the link 11 slides back one of the notches 13 catches the crank 19 and pulls it back to its original position, at which time one of the notches 12 will engage the detent12. A series of notches 13 are made, because the dump may be adjusted to rise to various heights, and if there were but one notch the link might not slide far enough forward to fall into engagement with the crank 19.

What l claim as new, and desire to secure by Letters Patent, is

1. In a horse-rake, the combination with an axle, a wheel-operated ratchet thereon, and a rake-head carrying a pawl arranged to engage IOO IIO

the ratchet, ot' an arm connected to the pawl and depending below the rake-head, a treadle having a push-rod arranged to strike the arm and throw the pawl in engagement with the ratchet, and a bracket secured to the frame of the rake and extending' under the rakehead adjacent said arm and carrying an adjustablestop located in the path of the arm, to stop the same and disengage the pawl.

2. In a horse-rake, in combination, a wheelaXle, a rake-head mounted thereon, means to engage the latter with the wheel to dump the rake, a slotted link connected to the rake-head and having notches, a detent engaging in one of the notches when the rake is dropped, and a treadle having a swinging projection working in the slot and arranged to lift and disengage the link when the treadle is depressed.

3. In a horse-rake, the combination with a rake-head and wheeled axle, and pawl-andratchet mechanism to connect the head and wheels to dump the rake, of a notched latch* notches on its lower( edge engaging a detent,

and a treadle havinga cranked rod extending into the slot to lift the link when the treadle is depressed.

In testimony whereof I have signed my n ame to this specilication in the presence ot' twosubscribing witnesses.
